Doug:
        Place a cap on the container with a cutout that barely allows the
head to go in and out. This will reduce the window for evaporation. Pieces
of sponge wick up the toluene and along with trapped gases will keep the
heads clean. I found out that liquid is not always necessary to keep a
chemical soft. The gas of a solvent will do good as well.
        Regards,        Ramon
